* performance/write-behind: reduce list-traversal during wb_mark_unwindsRaghavendra G2009-09-221-13/+19
| | | | | | | | | | - don't traverse entire request list to get the window-size, instead break when current window size becomes greater than configured limit. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 276 (write behind needs to be optimized.) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=276

* performance/write-behind: fine-tune logic of wb_mark_windsRaghavendra G2009-09-221-65/+14
| | | | | | | | | | | | | | | - remove wb_mark_wind_aggregegate_size_aware, since wb_mark_wind_all does the same work (with check for whether current aggregated data size is greater than the configured limit before calling it). Moreover, wb_mark_wind_aggregate_size_aware called __wb_get_aggregate_size redundantly, thereby reducing the performance, since for small sized large number of writes, traversing the list of requests takes significant amount of time.

* enhancement in write-behindAmar Tumballi2009-06-301-18/+22
| | | | | | | | | Write calls should not be pushed to background only when the mandatory locking is enabled, in all other cases (eg: O_SYNC, O_DIRECT etc), we should not be 'caching' any data, but the calls can be pushed to the background. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* write-behind: fix memory corruptionRaghavendra G2009-06-151-0/+1
| | | | | | | | - wb_sync did not set local = NULL after stack_wind. It also used to free local if its not NULL as part of cleanup process. Hence there was a double free in STACK_DESTROY done in wb_sync_cbk. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* write-behind aggregate-size related changesRaghavendra G2009-04-161-15/+76
| | | | | | | | | | | This patch brings in following changes: 1. make aggregate-size as non-configurable and make it to be equal to maximum iobuf size. 2. best effort to write data in chunks of length as close to aggregate-size as possible but not greater than aggregate-size, since aggregate-size is made equal to Maximum size of iobuf.
